At the moment I am not feeling very confident about what mark I will receive for hsc, and currently the atar cut off for Optometry is about 95 the last time I checked. If i was not to achieve this atar, are there any other ways to get into that field?
At my school our teachers encourage us to keep 12 units at least until mid-course, but it would be helpful to go into the hsc with 12 units just for precautions in case you stuff up a exam. You seem more than capable to achieve high marks with 12 units.
